" BLBND-SLAT ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 335,093, dated January 26, 1886.

Application filed October 20, 1885.

To a whom it may concern.-

Be it known that I, PETER RUND UIsT, of the city, county, and State of New York, have invented a new and useful Improvement in BlindSlat Adjusters, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part. of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a front elevation of a part of a blind to which my improvement has been applied, parts being broken away. Fig. 2 is a sectional plan view of the same, taken through the line 00 :c, Fig. 1. Fig. 3 is a front elevation of a part of the same, the cup'cap and the thumb-piece being removed. Fig. 4 is an elevation of the inner side of the cap-plate and the eccentric.

The object of this invention is to provide blind slat adjusters constructed in such a manner that the blind-slats can be readily adjusted at any desired angle.

The invention consists in the construction and combination of various parts of the blindslat adjuster, as will be hereinafter fully de scribed, and then pointed out in the claims.

A represents the frame of a blind, and B the blind-slats, which are pivoted to side strips,',--

0, attached to the inner edges of the blindframe A. The side strips, 0, are each made in two longitudinal parts, the plane of division running through the pivot-bearings for the slats B, as shown in Fig. 2, so that any desired slat can be readily removed and replaced by detaching parts of the said side strips.

To one end of each slat B is attached a headed pivot-pin, D, which passes through the side strips, 0, and is made of such a length that the head of the said pin will rest against the inner edge of the frame A, and will be held against the said edge by the side strip, 0, which is slightly countersunk to receive the said head, so that the said side strip will fit snugly against the said edge of the frame A. By this construction the slats B will be held from longitudinal movement, and will be held out of contact with the outer sides of the side strips, 0, and will thus be prevented from marring the paint upon the said side strips as the said slat-s are turned. To the other ends of the slats B are attached small cranks E, which rock in bearings in the adjacent edges Serial No. 180,424. (No model.)

of the parts of the sidestrip, O. The stems 5 of the cranks E are made with lugs F upon their opposite sides, which fit into recesses in the ends of the slats B, so that the said slats will be turned by and with thesaid cranks. The cranksE projectinto a longitudinal groove, G, in the inner edge of the side bar of the frame A, and are pivoted to a bar, H, also placed within the said groove, the said groove being made wide enough to allow the cranks E and bar H to have the necessary movement. 6

To the bar H is rigidly attached a pin, I, which projects through a slot in the inner ends, of a plate, J, placed in a recess in the side bar of the frame A, and pivoted at its outer end to the said side bar. The side edges of the plate J are bent outward to form flanges K, between which is fitted a disk, L, which is'secured eccentrically to the stem of the thumbpiece M. The stem of the thumb-piece M passes through a hole in the center of the bot: 7 5 tom of the cup capplate N, which is secured in a recess in the side bar of the frame A, and which is made of such a depth that the said thumb-piece will not project above the surface of the side bar of the frame, and of such 86 a size that the said thumb-piece can be readily grasped and operated to adjust the slat-s B at any desired inclination.

Having thus fully described my invention,

I claim as new and desire to secure by Letters 8 Patent- 1. In a blind-slat adjuster, the combination, with the frame A, the slats B, and the side strips, 0, ofthe cranks E, attached to the blindslats, the bar H, connecting the said cranks, and provided with a pin, I, the slotted and flanged pivoted plate J, the eccentric L, and the thumb-piece M, substantially as herein shown and described, whereby the blind slats can be readily adjusted to any desired angle, as set forth.

2. In a blind-slat adjuster, the combination, with the blind-slats B, having end recesses, of the cranks E, having side lugs, F, on their stems to engage with the said recessed ends {(0 of the slats, substantially as herein shown and described, whereby the said cranks are made to turn the said slats, as set forth.

PETER RUNDQUIST.
